When is an atom most stable?
Answer When the outermost shell(valence shell) is filled the atom is to be most stable. First Shell: holds up to 2 electrons Second Shell: holds up to 8 electrons Third Shell: holds up to 18 electrons Fourth Shell: holds up to 32 electrons
An atom does not need any electrons if it has outermost shell?
An atom needs electrons in its outermost shell to be stable. The number of electrons in the outer shell determines the atom's chemical properties and reactivity. If an atom's outer shell is complete, it is considered stable and less likely to react with other atoms.
How many electrons does a sulfur have in its outermost shell?
Sulphur has 6 electrons in its outermost shell.
Why are Sodium and Chlorine not stable elements?
Sodium and Chlorine are chemically unstable due to the amount of electrons each has in the outer shells (also known as layers) of their atoms. Sodium has 11 electrons. First shell: 2 electrons Second shell: 8 electrons Third shell: 1 electron As the number of electrons in the last shell is not 8 and as the shell is not full Sodium is chemically unstable. Chlorine has 17 electrons. They are arranged like this: First shell: 2 electrons Second shell: 8 electrons Third shell: 7 electrons The number of electrons in the last shell is not 8, and the shell is not full, and thus, chlorine is chemically unstable. To give an example of a chemically stable element, Argon has 8 atoms in its last shell, which is why it is chemically stable and therefore does not react with any element.
How many electrons does Xenon have in its outer electron shell?
Xenon has 8 electrons in its outermost electron shell, making it a stable noble gas.

Why it is said that outermost shell should contain 8 electrons?
According to the Octect Rule, an atom is most stable when its outermost shell has 8 electrons. So atoms try to attain 8 electrons in their outer shell.
How many electrons of the most stable have in there outer energy level?
The most stable atoms/ions have 8 electrons in their outermost shell.
How many electrons does a sulfur have in its outermost shell?
Sulphur has 6 electrons in its outermost shell.
An atom is stable when its outermost orbit is?
An atom is stable when its outermost orbit, or valence shell, is complete with the maximum number of electrons it can hold according to the octet rule. This typically means having eight electrons for most elements, except for hydrogen and helium which only need two electrons in their outer shell to be stable.
If the outermost electron shell of an element is not filled with electrons to its maxium capacity the element is not chemically active?
false

Xenon has 8 electrons in its outermost electron shell, making it a stable noble gas.
How many electrons does nitrogen have in its out most shell?
It has 5 electrons in its outermost shell.
How many electrons are in the outermost orbit of neon?
Neon has 8 electrons in its outermost orbit. The outermost orbit, also known as the valence shell, can hold a maximum of 8 electrons. Neon is a noble gas and has a full valence shell, making it stable and unreactive.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
